I shot at a deer with a 45-70 Handloaded with a 300gr. HP.
I never found a drop of blood.
I went to a gravel pit and took a few shots
the rifle was sighted in fine.
Either I had flinched or the bullet disintegrated after hitting a twig.
I decided that either way that rifle needed to go to somebody else. I replaced it with a 35 Whelen,
problem solved.

I like to do my hunting BEFORE I pull the trigger!
There is only one kind of dead, but there are many different kinds of wounded.
